Abstract
A cam assembly of a cam and a cam post replace each threaded fastener used in attaching a tube plate to a support ring of a bulk tank filter canister. A plurality of cam assemblies replace the threaded fasteners of the filter canister and enable the tube plate to be easily and quickly separated from the support ring when servicing the filter tubes suspended by the tube plate in the filter canister.
